The National Transportation Safety Board (NTSB) announced on Sunday that it is investigating an incident involving a Frontier Airlines aircraft that resulted in a fatal collision with a pedestrian during takeoff at Denver International Airport.
According to the airport’s social media update, the plane, which was headed from Denver to Los Angeles International Airport, reported the tragic collision at approximately 11:19 p.m. on Friday.
Following the incident, passengers were evacuated using emergency slides and then transported to the terminal by bus. An airport representative confirmed that 12 passengers sustained minor injuries, with five individuals requiring hospital treatment.
Passengers raised concerns about the evacuation process, citing delays in disembarking the smoke-filled aircraft and being left in the cold on the tarmac. Video footage showed some individuals descending the slides with their carry-on luggage.
NTSB spokesperson Sarah Taylor Sulick stated early Sunday that the agency is collecting information on the evacuation to assess whether it warrants a safety investigation. Further details are expected to be released in the coming hours.
Frontier Airlines didn’t respond early Sunday to a request for information about the evacuation.
The person, who authorities have still not identified, was hit two minutes after jumping the fence and crossing the runway. The person is not believed to be an airport employee.
“We’re stopping on the runway,” the pilot tells the control tower according to the site ATC.com. “We just hit somebody. We have an engine fire.”
The pilot tells the air traffic controller they have “231 souls” on board and that an “individual was walking across the runway.”
The air traffic controller responds that they are “rolling the trucks now” before the pilot tells the tower they “have smoke in the aircraft. We are going to evacuate on the runway.”
Frontier Airlines said in a statement that flight 4345 was the one involved in the collision and that “smoke was reported in the cabin and the pilots aborted takeoff.” It was not clear whether the smoke was linked to the collision.
The airline said the plane was carrying 224 passengers and seven crew members.
“We are investigating this incident and gathering more information in coordination with the airport and other safety authorities,” the airline said.
Passengers said panic took hold on the flight after an engine caught fire and the cabin began filling with smoke.
“Honestly, I thought I was going to die,” passenger Mohamed Hassan told Colorado’s 9NEWS.
“A lot of people next to me were screaming and crying. I just closed my eyes,” he said. “At that time, you’re not really thinking of anything, you know? Because we were just about to take off and I heard that boom, so I wasn’t sure what happened. I just thought something really, really bad happened.”
Passenger Nikil Thalanki told local media outlets that he felt “this jerk” as the plane was about to take off, adding that it felt like the wheels had left the ground but then came back down.
“There was fire on the engine. There was lots of sparks that are happening. Immediately came to a stop,” Thalanki said. “As soon as we saw the sparks on the flight, smoke filled the cabin completely. It was super hard to breathe.”
Kimberly Randle said passengers were panicking and desperate to get off the aircraft.
“In a few minutes, they finally opened the door. People were running to get out of the plane,” he said. “It was chaos everywhere.”
The NTSB has for years expressed concerned about evacuations, especially passengers leaving with their carry-ons. In an April report on the evacuation aboard a United Airlines flight at Houston’s George Bush Intercontinental Airport, the NTSB described a troubling scene.
Passengers were evacuated via slides and stairs last year from the jetliner after an engine problem during takeoff caused smoke and fire on the right wing.
Despite the flight attendant telling passengers to remain seated, several began shouting, “fire on the engine, let me get out!” That trigged “widespread panic” and prompted many passengers to get up and start retrieving their belongings. Some climbed over seats and began obstructing the aisle.
Three large men insisted the evacuation occur, pushing past a flight attendant and going down a slide before it had fully deployed – causing it to deflate and become unusable.
“Cabin crew training emphasizes assertive command presence and passenger control during evacuations; however, this event demonstrates how rapidly escalating passenger behavior can affect evacuation dynamics even in the absence of confirmed fire or smoke conditions,” according to the report.
The incident in Denver came a day after a Delta Air Lines employee was killed while on the job at the Orlando International Airport. In a statement, the airline said the employee was killed Thursday night without providing details of the incident or the name of the employee.
“We are focused on extending our full support to family and taking care of our Orlando team during this difficult time,” the airline said. “We are working with local authorities as a full investigation gets underway to determine what occurred.”
